Abstract

In the present study, premitotic period (G2)-delayed or blocked acinar cells were identified in the parotid gland of the neonatal rat. The noncycling G2 cells retain the potential to divide and respond to administration of the sympathomimetic amine, isoproterenol (IPR). The effects of IPR on suckling and weaned rats were compared. Both groups showed the presence of G2-acinar cells with a possible age-related change occurring after weaning.

摘要

在本研究中，在新生大鼠的腮腺中鉴定出有丝分裂前期（G2）延迟或阻滞的腺泡细胞。非周期性G2细胞保留了分裂的潜能，并对拟交感胺异丙肾上腺素（IPR）的给药有反应。比较了IPR对乳鼠和断奶大鼠的影响。两组均显示存在G2腺泡细胞，断奶后可能出现与年龄相关的变化。
